Biochemical Studies on Microorganisms. XV

Xv. a Study of Some Biochemical

A CHARACTERISTC of biochemistry is its great heritage of colour tests which have been devised to meet the demand for means of identifying substances of complex or unknown constitution where the more exact methods of pure organic chemistry were of no avail. Some of these biochemical tests are of a degree of delicacy and specificity almost comparable to biological reactions; but, owing to the dif...

Studies on Echinococcosis Xv : Secondary Multilocular Echinococcosis by Intrahepatic Inoculation

Biochemical Studies on Shock

During and following the production of shock by hemorrhage in the normal, suprareno-demedullated, and suprarenalectomized rat, the following significant changes in amino acid and carbohydrate metabolism have been observed. 1. In the intact, suprareno-demedullated, and suprarenalectomized rat there is a progressive rise in the whole blood and plasma amino acid nitrogen levels during and after a ...

Biochemical Studies on Inositol

In a previous publication (1, Paper V of this series) the purification and properties of the inositol-cleaving enzyme were described. It was shown that a highly purified enzyme was obtained from rat kidneys which cleaved inositol to D-ghCUI’OniC acid. The purified enzyme was shown to possess SH groups and 1 gram atom of iron per mole of enzyme. Both the SH groups and the iron are necessary for ...

Studies on the Fine Structure of Microorganisms

The fine structure of cells of Saccharomyces cerevisiae engaged in the formation of ascospores was studied in electron micrographs of ultrathin sections. Although the mode of the first reduction division could not be clearly determined, the second nuclear division appeared to proceed in a manner similar to that observed previously during vegetative division. That is, division by constriction of...
